A chlorine leak forced the evacuation of students and staff at Seymour High School, in Seymour, Conn. Friday, Feb. 24th, 2012. The fumes were caused when some containers with chlorine became wet during a delivery earlier in the day. The evacuation followed a two-hour delay caused by a snow, and students were eventually sent home for the day.

A wintry mix of rain and snow led to early dismissals at some schools, postponed several state tournament football games and created a bit of a messy commute across Southwestern Connecticut Tuesday night.

Most of the region received from a coating of a snow up to 1 or 2 inches, but 3 or 4 inches fell in some higher elevations in the state. The heaviest bands of snow moved through Fairfield and New Haven counties around 6 p.m. as temperatures dropped.

The National Weather Service issued a winter weather advisory for Fairfield and New Haven counties that expired at 8 p.m., but warned that travel conditions could remain treacherous throughout the night.

"After the precipitation ends, the other concern is refreezing and black ice," said WTNH News 8 meteorologist Quincy Vagell. "Roadways right down to the coast will become icy."

Vagell said the slippery conditions could still be in place for the early morning commute Wednesday.

As the storm moved into the area Tuesday afternoon, many schools in the Naugatuck Valley, the Danbury area, along with Wilton and New Canaan let students out early. The Connecticut Interscholastic Athletic Conference postponed all but four of the sixteen state championship football games set to be played Tuesday night. The delayed games were moved to Wednesday.

Several minor crashes were reported by local and state police, and the precipitation intensified normal rush hour delays on state roads, including Interstate 95, the Merritt Parkway and Route 8. The roads were slick in some spots, despite pre-treatment by state Department of Transportation crews.

The storm was expected to fully move out of the region by midnight, while snow could continue in some inland, eastern portions of the state until the early morning.

Wednesday is forecast to be sunny, but breezy and chilly. Highs will be between 38 to 42. The forecast for the remainder of the week is similar, with temperatures in the high 30s or low 40s and no rain or snow expected.
